Q. The term Ecosystem was proposed by:
Answer: A. G. Tansley
Notes: The term “ecosystem” was first coined by Roy Clapham in 1930, but it was ecologist Arthur Tansley who fully defined the ecosystem concept. In his classic article of 1935, Tansley defined ecosystems as “The whole system,… including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment.”
